I second what Lonestar648 said,Now is all there is!
I honestly don't think that the really expensive upgrade for the Premium Service is worth it.
Ride this train in the Winter from Vancouver to Toronto when the consist is much smaller, the Train is uncrowded and the price is right, especially if you book a Lower Berth which is Very comfortable and you still get all the benefits except the free booze and a reserved seat in the Park Car Dome which,IMO,aren't worth several thousand dollars additional!
Book it Danno!
I've heard great things about the Canadian's open sections, but I think I'd be kind of nervous spending four nights in an open car. Looking more at the Prestige rooms, they seem incredibly nice, but almost $10K for two people one way in a room with only one bed, is a tad...ridiculous. That would be a once in a lifetime thing (at best) for almost anyone.
To get a sense of how that compares to Amtrak, my dream cross country trip would be:
Cardinal (roomette) - EB or CZ (Family Bedroom) - Coast Starlight (roomette) - Sunset/Eagle (Family Bedroom) - Cardinal (Roomette)
That would total out at around $2500 for two people. So a Prestige room on the Canadian would cost around four times as much, have either half or a quarter the beds, and go less than half the distance. I could ride every LD train in the country end to end for around half what they charge for Prestige on the Canadian. That just seems unjustifiable.
